POURING SPOUT FOR CONTAINERS Filed Jan. 22, 1929 r I Patented June 24, 1930 UNITED STATES PATENT OFFICE CHARLES J. A'U'LBACH, OF IPASSAIC, NEW JERSEY, ASSIGNOB TO CONTINENTAL CAN COMPANY, ZDTCL, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK POURING SPOUT FOR CONTAINERS Application filed January 22, 1929. Serial No. 334,236.

The invention relates to new and useful provements 1n pouring spouts for containers.

An object of the invention is to provide a container having a nozzle with a pouring spout which is hingedly supported within the container so that said pouring spout may be housed within the nozzle or swung to a position projecting from'the nozzle for pouring. I

A further object of the invention is to provide a pouring spout for a container of the above type with means for yieldinglysupporting said spout in pouring position.

A still further object of the invention is to provide a pouring spout for a container of the above type which is provided with means for draining any fluid dripping from the pouring spout or otherwise collecting in the space between the spout and the nozzle.

In the drawings Fig. 1 is a perspective showing one form of container with the improved pouring spout connected thereto and in projected position for pouring. V

Fig. 2 is a sectional view through the nozzle and a portion of the container showing the pouring spout as swung inwardly and housed within thenozzle.

Fig. 3 is a View showing a portion of the nozzle in section and a portion of the container with the spout swung to pouring position and secured in said position by yielding means, and with the end of the container domed so as to substantially house the securing means on the inner face of the end.

The invention is directed to a pouring spout for a container having a projecting nozzle and consists in a supporting means for the pouring spout so that said spout may be hingedly connected to the container within the container and arranged so that the spout may swing from a position where spout is also provided with a slot or 0 ening in the side wall thereof through'w ich any liquid dripping from the spout into the channel or recess between the spout and the nozzle will drain back into the containor.

Referring more in detail to the drawings, the invention is shown as applied to a square container indicated at l in the drawings. The container is provided with the usual type of nozzle 2 to which a cap 3 is secured by suitable means for closin the nozzle. Within the cap is a sealing 'sc 4 so that when the cap is screwed onto the nozzle the sealing disc is firmly pressed against the hollow bead 5 at the extreme outer end of the nozzle and thus the container sealed. The securing means, as shown in the drawings, consists in interrupted thread portions 6. A continuous thread may be used or any form of connection may be used for securing the cap to the nozzle of the container. The nozzle is seated against the outer face of the end 1 of the container and secured thereto by solder.

The pouring spout is indicated at 7 in the drawings and includes a tubular portion which is extended and provided with a pouring lip 8 which may be shaped in any suitable way. This pouring spout is provided with a projecting flange 9 at its inner end and a reinforcing ring 10 is secured to said flange. Projecting from said ring is a hinge member 11 located at the side of the spout directly beneath the pouring lip 8. Attached to the end 1 of the container is a supporting ring 12. Said ring is soldered in any suitable way to the container so as to become a rigid attachment thereto. This supporting ring is provided with a depending hinge member 13 to which the hinge member 11 is secured by a suitable pivot pin 14. The spout is proportioned and hinged to the nozzle so that when swung to its extreme inner position, as shownin Fig. 2, the outer end of the spout rests against the side wall of the nozzle and the spout is completely housed within the nozzle. After the closure has been removed from the container, the spout is readily reachable so that it may be swung to the pouring position indicated in Fig. 3. The supporting ring 12 for the nozzle is provided with yielding spring members 15, 15. Each member is formed with inclined parts leading to a shoulder 16. When the spout is swung to pouring position the reinforcing ring 10 engages the under inclined face of this yielding lug and springs the lug so as to pass by the shoulder. The lug will at once spring back beneath the reinforcing ring and thus serve as a yielding means for holding the spout in pouring position.

A packing 17 is placed on the reinforcing ring 10 at the base of the spout and when the spout is swung to pouring position, this packing will be clamped against an annular shoulder 18 formed in the ring 12 which supports the spout. The purpose of this packing is to provide a sealing engagement between the spout and the end of the container so as to insure all the liquid when being dispensed passing through the spout.

The spout is provided with an opening 19 in the wall thereof opposite the lip 8. The purpose of this opening which extends all the way to the .bottom of the spout is to,

permit any liquid gathering in the recess or channel 20 between the pouring spout and the nozzle when said spout is in pouring position to drain back into the container. By placing the opening in the wall) of the spout opposite the lip and at the base thereof, none of the liquid being dispensed will pass through said opening so as to drip from the nozzle during pouring.

It sometimes occurs that liquid will drip from the nozzle when the container is returned to upright position and the nozzle still retained in pouring position relative to the container. This drip is the liquid which is collected and drained back into the container.

In Fig. 3, I have shown the end of the From the above, it will be apparent that- I have provided a pouring spout for a container having a nozzle which may be closed and the container sealed. The pour- I ing spout when the container is sealed is housed within the nozzle out of sight and is always with the container ready to be placed in pouring position. When the container is opened, the nozzle may be readily reached and swung to pouring position meaoee where it will be yieldingly held. When the nozzle is in pouring position it is substantially liquid-sealed against the inner wall of the container so that all liquid passing from the container must pass into the spout and over the pouring lip of the spout.

By this construction of pouring spout, I have provided a container which may be readily reclosed and sealed after the container has been opened, and thus it is that the container is especially adapted for the storing and dispensing of volatile liquids which must be held under seal to prevent evaporation.

It is obvious that minor changes in the ing, said pouring spoutbeing provided with a gasket whereby a sealing. engagement with .the container is provided so that the liquid to be dispensed is compelled to pass through the pouring spout, and an independent yielding means for holding said spout in pouring position and sealing engagement with the end of the container.

2. A container comprising a projecting nozzle, means for closing the same, a spout having a pouring lip, said spoutbeing hingedly supported within said container and adapted to swing from a position completely housed within said nozzle to a position projecting from said nozzle for pouring, said spout having a sealing engagement with the end of the container when in pouring position so as to insure the liquid being dispensed passing through the spout, the wall of the spout opposite said lip having an opening therethrough at the base 0 the spout whereby liquid collecting in the channel between the spout and the nozzle will drain back into the container. V

3. A container comprising a projecting nozzle, means for closing the same, a pouring spout provided with a pouring lip adapted to be housed within the nozzle so that said nozzle can be sealed and adapted to project from said nozzle when in pouring position, said nozzle when in pouring position having a sealing engagement with'the end of the container so as to insure all liquid being dispensedpassing through the nozzle, said spout having an opening in the Wall thereof opposite the pouring lip and.

at the base of the nozzle whereby liquid collecting in the channel between the spout and the nozzle will drain back into the container.

4. A container comprising a body portion having a projectin nozzle, means for closing and sealing sai nozzle, a pouring spout hingedly supported within said container and adapted to swing from a position completely housed within said nozzle and con tainer to a position projecting from said nozzle for pouring, and an independent yielding means for holding said spout in pouring position.

5. A container comprising a body portion having a projecting nozzle, means for closing and sealing said nozzle, a pouring spout hingedly supported within said container and adapted to swing from a position completely housed within said nozzle and con tainer to a position projecting from said nozzle for pouring, and an independent yielding means for holding said spout in pouring position, said spout having a pouring lip at one side thereof and an opening therethrough at the base of the spout at the other side thereof whereby the liquid collecting in the channel between the spout and the nozzle will drain back into the container.

In testimony whereof, I aflix my signature.
